Paetongtarn Shinawatra (37) became Thailand's youngest PM after receiving a royal letter of endorsement on Sunday

Paetongtarn is the youngest daughter of billionaire and former PM Thaksin Shinawatra. She is also the niece of former PM Yingluck Shinawatra

She is Thailand's second female PM and the country's third leader from the Shinawatra family

She is married to Pidok Sooksawas, a commercial pilot. She has professional experience of handling the Shinawatra family's business empire

Known by the nickname Ing, Paetongtarn formally started her political career when she joined Pheu Thai in 2021

Thaksin was the first Thai politician ever to win an overall majority of seats. His residual popularity is a factor behind the support for Paetongtarn
